Are there any Kohler socket wrenches for a old Kohler shower valve. I bought the shower socket set and since the metal is thin I have already rounded two of them and still have not gotten out the valve to replace. The size I need is 30/32in deep socket

You need to buy a heavy duty 15/16” deep socket if it is short cut the shank of the stem it works great and replace the stem with a new one, Good luck.
